Opera 9 - is really good !
Opera was once my favorite browser, during the time I was accessing internet using dial-up connection. Opera was damn fast and pages loaded quickly at that time.
Later, when IE and Firefox got a stronghold and broadband slowly came in, I stopped using Opera coz, it does not support all CSS, javascript functions.
Recently I came across Opera 9 and I am so happy with it ! It supports all the latest style specs, excellent javascript support and the damn cool rendering speed. Best of all, it is FREE ! 
The guys at Opera has learned over the years. Hope Opera soon becomes one of the standard browsers in the list.
Keep up guys. It’s cool !
